Mark wants to paint a mural. He has 1 1/4 gallons of yellow paint, 1 1/5 gallons of green paint and 7/8 gallon
of blue paint. Mark plans to use 3/4 gallon of each paint color. How many gallons of paint will he have left
after painting the mural? Enter your answer as a simplified fraction.
+36916 LCM 4 5 8 = 40 convert to denominator 40
yellow = 50/40 green = 48/40 blue = 35/40
total ( 50 + 48 + 35) / 40 = 133/40
Now use 3/4 gal of each ( 3/4 is 30 /40 )
133/40 - 3 * 30/40 = 43/40 = 1 3/40 gal paint left
